When you are generating maps for publication, you may want to display the cave passages as a solid, filled color. This is because black and white images and inexpensive printers may make it difficult to see the finer details; particularly, if you are working with a large cave. As a result, the Viewer allows you to fill the Spline Curve passages with color. In this mode, the passage models form continuous, solid passages filled with color.
Options. To enable the mode, select the “Filled Splines” option in the Passage Modeling window. You can set the fill color by selecting the Preferences->Set Colors and Fontsoption from the menu bar. It can be also useful to set the Passage Wall color to contrast or highlight the fill color. Finally, you can also color the fill according to its depth using the Color-by-depth.
